Description
The new PAC-2G3 is a clip-on amplifier which works in the 2GHz band. It is
used together with SVP Broadcast Microwave’s camera transmitters,
allowing the coverage of wider areas.
It can be used with neatly all camera transmitters as it can have V or AB
battery adapter plates. This small and powerful amplifier expands the
possibilities of the wireless camera transmitters. Just by adding this low
weight and compact amplifier to a camera transmitter medium range links
can be possible.
This amplifier can be 1Watt or 3 Watt output (PAC-2G3) or from 0.5 Watt to
1 Watt output (PAC-3G3), selectable from a switch in the front panel. Input
signal level has to be in the range of 10 to 100MWatt, as it has 10 dB ALC.
So the output power is not dependant on the input signal level as long as
the input signal level is in the range from 10 to 100mWatt.
This solid state LDMOS amplifier has been designed and optimized for use
with COFDM digital video signals. The low intermodulation and our
proprietary pre-distortion technique provide an excellent linearity and better
ACP performance. The predistortion technique enables higher power output
maintaining transmitted signal quality.
The amplifier can be powered through the V or AB battery adapter plates or
through a DC power supply connector, which accepts input power voltage
from 11 to 28 V.DC
The PAC-2G3 amplifier is protected against polarity reverse and over
voltage. It also has thermal protection with auto reset.
The equipment has also two Leds (Out. Level and DC), that show the
equipment’s operation state. The information provided by these two Leds is
described below:
DC Power supply Led: lights in green: The amplifier is powered.
Ouput Power Led: lights in green when the output power is set level.
The low intermodulation, the excellent RF performance and the high
reliability make this amplifier especially interesting for most demanding
wireless camera link applications.
